The benefit of DNS Master is that one no longer needs to memorize the ip address to access a domain. The DNS Master will translate or translate ip addresses into a domain name and vice versa because DNS master is the one who holds the complete list of a domain it manages. While the benefits of DNS Slave is a backup of DNS Master. The DNS Slave is a backup DNS if our primary DNS occurs damage. There will be mutual transfer of information between the primary DNS and the DNS slave. The steps to build a Slave DNS are as follows: Set up a new DNS server, the old DNS server keeps running. For configuring the DNS Slave, we must first install DNS with the same steps as in DNS Server. We have to install bind9 first and then do the Slave DNS configuration. Edit and add configuration for forward and reverse on named.conf.local file. Finally, restart the daemon from bind9. The dns master should be rebooted after the dns slave finishes in settings.

Hello world. Previously I posted a post about installation and  configuration of DNS . Today I’d like to share you how to build  two or more domain in one server. Here we go. Firstly, Edit /etc/bind/named.conf.local file and  add virtual domain configuration. Create a file virtualdomain.conf in the directory that has been specified and fill in the domain name that will be created, eg domain admin.info and jarkom.info and so on. Create two domain files are copied from existing filedomain eg db.takehome.com. Next restart the dns server Perform testing by ping to a new domain.

Hello guys, this time I’d like to share step by step DNS on server side and client side using linux ubuntu. If you still do not know what exactly DNS is, you can read our previous post in here . Then here you go. Server Side Log in as root on terminal Perform the installation package with the command After installing the package above configuration file will be created in /etc/bind then read the file named.conf, named.conf.local and named.conf.option. The following is the contents of the named.conf file, it is not necessarily a change to this file. Next there is the file named.conf.local, initially the contents of this file is still empty, fill with domain zones we will make and reverse domain as follows (in this case we will make domain takehome.com): The file named.conf.option contains additional options on our domain, add our main DNS here so that allows the client can connect to the internet: Next, prepare two files according to the conten...

What is Domain Name Server (DNS) ? The DNS server enters IP into the name of the address and vice versa from the name of the address to the IP number. Some ways to translate internet addresses include: Read local file / etc / hosts Utilizing DNS Server service The local / etc / hosts file contains a list of translation names to machine IP machine addresses that can be used also to translate IP addresses to names. By having this file, the Linux machine can use a more memorable name to call or access another machine on the network, instead of having to use an IP number. However this naming is only known locally on the computer in question. This file is very simple, its contents as in the following example: Explanation : Column 1 is an IP number Column 2 is FQDN (Fully Qualified Domain Name) Column 3 is the hostname The disadvantage of using the / etc / hosts file is : All machines or hosts in the network must have an identical file / etc / hosts Eve...
